I will talk about the problems with non-normalized text (such as NFD) in WordPress at a forthcoming WordCamp and I would be really happy to show how great this is handled by Gutenberg. Any chance to get this fixed in the next months?

Hey @Mamaduka - that's correct!

Was fixed in Changeset 53754 and confirmed in my comment on #30130

Sorry for not closing this issue myself.
